Mullions

Use the grid on a curtain wall to place mullions.

Architecture tabBuild panel (Mullion)

When you add mullions to a grid, the mullions resize to fit the grid. If you add a mullion to an inside grid, the mullion is centered on the grid. If you add a mullion to a perimeter grid, the mullion aligns so its border is flush with the outside of the wall.
